I have only tried this with my Garmin 705, but it works well with that.

Needless to say that if you're in the majority and ride an upright bike that this will work out of the box for you.

But I ride a recumbent bike, and the pedals (where cadence is measured) are about five feet from the rear wheel (where speed should be measured). Thus the cadence and speed sensors need to be separated. Nobody actually makes a speed/cadence sensor that has this separation, and it's very hard to find separate cadence and speed sensors. And if I could find separates I'm not sure my Garmin 705 would work with them both at the same time.

I bought this sensor because when I asked Wahoo support about it they told me I could just snip the wire between the two sensors, splice in a longer two conductor wire, and all will be fine. No special kind of wire needed, so buy whatever looks good with your bike. I don't know whether their legal department would claim they "support" this, but I was pleased that they were open and honest about the modification.

I'm handy with soldering iron, so this mod was easy for me to do.

I have also read that you can do a similar modification with the Garmin GSC 10 Speed/Cadence Bike Sensor. The problem with modding the Garmin is that you need to cut the housing, and then you need to figure out some way to seal those two separate pieces from moisture, and jury rig a mount for the cadence sensor. The Wahoo makes this easier since it is already two separate pieces that are sealed and both designed to be mounted. The only thing you need to moisture seal is your modified cable.

The sensor was easy to install and setup, once I visited their site and looked at the installation instructions there. Those included with the unit are a little lackluster, but there is a pdf on the wahoo fitness site that makes it very easy. I was up and running in 15 min. After getting it on the bike the calibration was 2 clicks and I was off and running. I strongly suggest a cadence meter for anyone doing cycling, really gives you the data you need to be a better biker.

Bought this product to enable my iPhone 4s to track my bike rides with the mapmyride app. I have found the included Wahoo fitness app is better than the mammy ride app for tracking Heart rate monitor data. Works flawlessly and set up was easier than expected.

I bought this sensor to pair up with my Timex Global Trainer GPS watch so that I can track "distance", speed and cadence while my bike is on the trainer. It took me about 20-25 minutes to install, and I am not a bike tech, just a regular bike rider. It works really well as an ANT+ transmitter that sends speed/cadence info to my watch which acts as the ANT+ receiver. If you are looking for a wireless ANT+ sensor that you can pair up with a watch or other ANT+ receiver, this fits the bill and works really well. If you just want a speed/cadence sensor for tracking your workouts while on a bike trainer, get the Cateye Strada Cadence (wired). Typically I wouldn't need this while on the road, since my watch has GPS and can track speed/distance as well as map my ride AND/OR I can use an app like RunKeeper or Strava on my Android phone. The only thing it would add would be cadence, which is not that important to me when I'm on the road enjoying the ride.

installation is simple and straightforward - all hardware is provided, you don't even need instructions, just mount both speed and cadence sensor on the chainstay and secure with zipties. Syncs with Ant+ receiver (in my case Bontrager Node 2) seamlessly, no problems whatsoever. 100 miles ridden, everything works as expected. You may want to adjust positions of the sensors and magnets to guarantee good signal pickup

I purchased the Wahoo WFSC01 because the crank arms on my Bacchetta Corsa 700c recumbent are too far from the frame to use the Garmin sensor. The Wahoo works perfectly with my Garmin Edge 705. The speed sensor is mounted on my front fork, and the wheel magnet triggers it. (The following will mostly be of interest to recumbent riders). The cadence sensor required an easy modification of the cable connecting it to the speed sensor. I cut the cable, added an appropriate length (about 18") of 2 conductor black cable, and added a magnet to the back of the inner chainring. I soldered the connections, though crimps would work. I covered the connections with heat shrink tubing available in any electronic supply. A butane lighter will shrink it, making for a neat, water-tight extension. (Don't forget to slide the heat shrink tubing up the original wire before you make the connections!). The sensor is mounted to the frame up front, behind the crankset, and the magnet triggers the cadence sensor reliably. Although Wahoo provides zip ties, I needed a few longer ones and some extras to clean up my unusual installation.

I have owned this sensor for a bit more than a year now, and mostly it works as one would expect it to. However I often have a problem of it stopping sending speed/cadence data for a few seconds (usually 4-7 seconds), which causes my bicycle computer to stop recording all data (including power) during these few seconds (since it's recording only when speed is non-zero), which is a bit annoying.

The design lets you place the speed and cadence sensors more or less independently, which is a plus, however the mounting pads work best only if have chain stays that are more or less round. If your chain stays have some kind of angular profile (probably with small bevels), it may be hard to position the speed sensor so that it is stable enough.

Works like a charm on my stationary bike. I use it to connect to Endomondo on my Galaxy S4 (be advised, though, that Endomondo can't currently persistently read speed from the sensor. They're working on it, apparently. Cadence readings are flawless, though, so it's not Wahoo's fault.)

When I needed Wahoo's support to help me install the device in my setting (which isn't standard), the reply was prompt and informative.

I only wish the cord were a little longer (though I can see that they have to strike a balance here).

This is a perfect sensor pack for a Salsa Vaya. The 2 piece layout makes a custom set easy. The braze-on cable tie-downs on the Vaya's chain stays make it difficult to put the all-in-one unit on the bike, add a small crank set to the mix and the Wahoo unit is the perfect sensor. This is the second one I own (2 Bikes), it has given me the least trouble with movement and lost signals. We ride a lot of Rail Trails and it has held up to the off road use with no issues.

This item was bought with the wahoo case for the iPhone and the heart rate monitor. The heart rate monitor quit in about 6 months never to talk to the wahoo case again. The speed and cadence pickup lasted 1 year and one month, 30 days outside the warranty period. The sensor started cutting out at times the last month of use. I replaced the battery but no help. This is a good product just short lived.
